Every new identity staking verification creates a verifiable signal, routing validation through a localized trust oasis. Creating pseudonyms triggers exponential capital exhaustion, making attacks cost O(2^n) while legitimate interaction remains light as a zephyr.","stamp":2,"from":"poa15WUB9a7NDyTqRfPAJbzkyoCW5gXRYdS6d95DW7mMRK6U","nonce":8,"parents":["0191c7a85e231ed5278682b61ec97a5843b8af3e83beb4e97b3168191db66080","12bb96b3cffe313eab5a96533dc142d82f6c7181bede1dd0d36905d8e6d4ceda"],"ts":1793206727,"cid":"poa-mainnet-1","sig":"YCjux8yudfz7d6nj4CEhdVoHAJTYVkbiW4APo8uUYJzv1XapoxydV7oNtd4xtk8L6MYhskRAesHE3Sp1gqRZaAa"},"checkpointed":{"height":119646,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T22:39:24.743Z","checkpoint_height":119646,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
